Question

The solubility of solid solutes depends on temperature. As temperature increases,

• A. the solubility of most solid solutes increases.
• B. the solubility of most solid solutes decreases.
• C. the solubility of most solid solutes does not vary.
• D. the solubility of most solid solutes drops to zero.

Answer 1

The correct option is A the solubility of most solid solutes increases.

For most solids dissolved in liquid, their solubility increases with increase in temperature.
On increasing temperature the kinetic energy of the solvent particles increases and they are able to break apart effectively. The solute particles are held effectively between the solvent molecules thus increasing the solubility.
